Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices experience irregularities in image display due to variations in kickback voltages, which are not effectively addressed by existing technologies, leading to stains and reduced display area efficiency.
Innovation Solution
The implementation of a display device design that includes different cell gaps for normal and kickback pixels, with kickback pixels adjacent to signal lines and configured to display different colors, and normal pixels with larger cell gaps to minimize the impact of kickback voltages, thereby reducing dead space and preventing image irregularities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different cell gaps are provided for kickback pixels and normal pixels, then image stains caused by kickback voltage variations are minimized or prevented, but device complexity increases
Solution Approach 1:
The patent applies local quality by providing different cell gaps specifically for kickback pixels adjacent to signal lines, while normal pixels maintain a standard cell gap. This localized differentiation compensates for kickback voltage effects only where needed, improving image quality without unnecessarily complicating the entire display structure.
Solution Approach 2:
The patent changes the physical parameter of cell gap to compensate for kickback voltage variations. By adjusting the cell gap parameter for specific pixels experiencing kickback effects, the invention achieves uniform image display without requiring complex circuitry or control mechanisms.
2Reliability
If kickback pixels with smaller cell gaps are used, then kickback voltage effects are compensated, but manufacturing precision requirements increase
Solution Approach 1:
The patent implements local quality by differentiating cell gaps only for kickback pixels adjacent to signal lines, while normal pixels use standard cell gaps. This approach concentrates manufacturing precision requirements to specific locations rather than requiring uniform high precision across the entire display panel.
